Binary Sequence-Based Fault Detection in Linear Antenna Array

Present article investigates a binary sequence-based (BS) method of fault detection for linear antenna array. The method considers generation of possible combination of binary sequence depending on number of elements of the array. Based on the binary sequence generated corresponding array factor is calculated and compared with the reference array factor which happens to be array factor of faulty linear antenna array. Once the suitable match is anticipated, number of faulty elements along with their respective locations can be obtained. Effectiveness of the method has been demonstrated with 12 elements linear antenna array with both uniform and non-uniform excitation with different faulty elements position. Acceptability of the method has been illustrated through comparative study with previously reported fault detection methods. All the simulations are carried out using MATLAB simulator version R2020a on desktop with 16 GB RAM and Intel® Core™ i7-9700F Processor.
